2.4 No Implicit Trust Escalation

Description

Trust MUST NOT transitively escalate between agents.

Rationale

Transitive trust creates attack paths where compromising one agent leads to access to others.

Audit Procedure

1. Map all agent-to-agent trust relationships
2. Identify transitive trust chains
3. Test for trust escalation

Remediation

1. Implement explicit trust grants
2. Validate identity at each hop
3. Use trust scoring that degrades with hops
